does anyone know how many episodes season 2 will have? cuz i checked anime network and it says "we have 13" but crunchy only has 6 or 7 and season 1 had like 52 episodes or sumthing.... well does anyone know how many episodes it will have?

When it says "we have 13", that probably just means that there are currently 13 episodes that have titles so far. Some of those 13 are unaired yet, but they already have a title. There are probably going to be more episodes than 13.

Some series producers do not give out the total number of episodes until much later, so (as LanceSP said) some online databases would only mark episodes to which they have the titles of episodes. Crunchyroll only lists 6 episodes, because the 6th episode recently aired in Japan.
